Specification of Letters Patent No. 2,764, dated August 26, 1842.

T all whom may concern:

Be 1t known that we, SOLOMON M. Eer,

i of Paint township, lVayne county, Ohio,iand

DAVID N. PHELPS, of Jefferson township, Richland county, State of Ohio, have invented anew and useful Improvementin Rotary Steam-Engines, which is described as follows, referencebeing `hadvto the annexed drawingsiof the same, makingpartof t-his specification.

Figure l is a perspective view of the engine. Fig. 2l is a perspective view of the revolving steam wheel detached from the stationary cylinder.` Fig. 3 is a perspective view of the stationary head and steam boX detached from the interior of the fixed cylinder. Fig. t isa perspective view of one of the sliding perforated heads or `pistons separated from the steam wheel. Fig. 5 is a vertical cross section. y Similar; `letters refer to corresponding parts. Y c l The nature of our inventionconsists in the peculiar `construction ofthe engine by which a regular rotarymotion of the wheel is produced by the direct action of t-he y steam to sliding` heads of said wheel.

The stationary cylinder A Figs. l and 5 in which the wheel B revolves is circular on the outside and eccentricon the inside,

the eccentricity of form of the interior be ing producedbya semi-circular head C` tapered at each end so as to formtwo in` `clinedplanes and recessed in the" middle forming a steam chamber D Figs. 3 and 5. The said semi-circular head O is fastened i securely to the interior of the cylinder` by screws or in any convenient way.` The thickest portions of the head C next to the steam chamber form shoulders Gr corresponding with the circumference of the wheel B against which theyfit perfectly,

any wear or openings produced by the rubbing of the wheel against said shoulders or portions Gr beingclosed by sliding blocks of metallic or other packing forced against the wheel by screws or other suitable means. A steam wayE Fig. 5 is made through this head and through the cylinder A and cap P for the introduction of` the steam to the steam chamber D.

An escape aperture` F for the discharge of the steam after it has performed its in-` tended oiiice is made through the cylinder about one fourth its circumference from the cylinder'A opposite the shoulder G and the said shoulder Gr.` This valve isper-f forated obliquely with an opening 7c for the passage ofthe steam from one side of the valve to the other.

rIhe `groove in the wheel in which it moves is" enlarged `near the circumference of" the wheel forming steam ways I for thepassage of the steam through the steam wheel and valve from one side to the other of thevalve. Thel wheel is as long as the width of the iiXed head to 4which it isfitted and against which it revolves. Both wheel and head `are embraced or` inclosed by two` circular `parallel plates L Figs.' 1 and 2 fixed to and revolvingwith the shaft of the wheel, of a s diameterV equal to that of the interior of the regular part of the fixed cylinder which i confines the steam between said plates until itescapesat the eduction pipe f the joints between the inside of thecylind'er and the outside of-thecircular plates L being packed by circular rings of packing M.

The shoulders G Fig. 5 must be wider than themortises J so as to cover the lower opening while the upper one is fopen to receive steam, said shoulders being so arranged as to embrace a space a little greater than one fourth the circumference of the cylinder.

The operation of this engine is as follows: The steam from the boiler is conducted by the induction tube H to the chamber D. in the stationary head C where it presses uponthe end of the sliding piston K immediately after passing the shoulder Grand forces the other end of the piston out of the groove in the wheel and against the inside of the cylinder where it is held, making a close joint without requiring any packing and as the end of the piston wears the steam still forcing it against the inside of the cylinder, thereby compensating for the wear of the ist-on, the steam simultaneously passing obiquely through the piston from one side thereo-f to the opposite side against which it acts simultaneously and at right angles thereto, the steam being confined between the piston and the stationary head, driving the said end of the piston around within the cylinder in the direction of the arrow No. l until it arrives at the escape opening F through which and the eduction tube f the steam escapes ,into the atmosphere at the same time in performing its rotary motion carrying with it the wheel and shaft from which the Vrotary Vmotion desired is obtained, and when the last mentioned end of the sliding valve arrives atI the inclined plane of the fixed head it is forced into the groove to be acted on by .the steam in the same manner as the first mentioned end as soon as it passes the aforesaid shoulder Gr at the same time forcing the first mentioned end of the piston out of said groove in like manner as above set forth, the steam passing from one side of the sliding piston .well with a balance wheel to equalize the rotary motion of the wheel, yet it will be Vevident to the engineer that two wheels and valves may be applied to the same shaft (as the use of only one sliding piston. The arrangement however need not be limited to one or two wheels and valves on the same shaft; they may be extended to three, four,

or more having the valves arranged so as to have the commencement of the action of the steam take place at different periods of time, but these and the corresponding circular plates and fixed heads being all constructed like those above described will render any further description unnecessary.

What We claim as our invention and which we vdesire to secure by Letters Patent Passing the steam through the revolving wheel and sliding piston from one side to the other causing the steam to act simultaneously against the end of the piston in passing the steam chamber in the fixed head and against the flat side of the opposite end of the piston in passing through the interior of the cylinder, thus forcing vout" the piston from the wheel and closing the joints between the flat side and end of the sliding valve and the surfaces of the wheel and cylinder against which they are pressed byy the steam and thus turning the wheel and shaft by the expansive force of the steam without the use of any packing at the aforementioned joints or,l the application of other power in the manner herein set forth; or in any other: mode subst-an-ltially the same. y
